The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Fix boot crash on Raspberry Pi by moving the update to `event->datalen`
before data is copied into flexible-array member `data` via `memcpy()`.
Flexible-array member `data` was annotated with `__counted_by(datalen)`
in commit 62d19b3580 ("wifi: brcmfmac: fweh: Add __counted_by for
struct brcmf_fweh_queue_item and use struct_size()"). The intention of
this is to gain visibility into the size of `data` at run-time through
its _counter_ (in this case `datalen`), and with this have its accesses
bounds-checked at run-time via CONFIG_FORTIFY_SOURCE and
CONFIG_UBSAN_BOUNDS.
To effectively accomplish the above, we shall update the counter
(`datalen`), before the first access to the flexible array (`data`),
which was also done in the mentioned commit.
However, commit edec428219 ("wifi: brcmfmac: allow per-vendor event
handling") inadvertently caused a buffer overflow, detected by
FORTIFY_SOURCE. It moved the `event->datalen = datalen;` update to after
the first `data` access, at which point `event->datalen` was not yet
updated from zero (after calling `kzalloc()`), leading to the overflow
issue.
This fix repositions the `event->datalen = datalen;` update before
accessing `data`, restoring the intended buffer overflow protection. :)

we just pick the first one that already exists.
Sadly, in AWS Linux there are no files directly under /lib/firmware,
only in subdirectories. Don't limit the search to -maxdepth 1.
We can use the %P print format to get the correct path for files
inside subdirectories:
$ find /lib/firmware -type f -printf '%P\n' | head -1
intel-ucode/06-1a-05
The full path is /lib/firmware/intel-ucode/06-1a-05

This devm API takes a consumer device as an argument to setup the devm
action, but throws it away when calling further into gpiolib. This leads
to odd debug messages like this:
(NULL device *): using DT '/gpio-keys/switch-pen-insert' for '(null)' GPIO lookup
Let's pass the consumer device down, by directly calling what
fwnode_gpiod_get_index() calls but pass the device used for devm. This
changes the message to look like this instead:
gpio-keys gpio-keys: using DT '/gpio-keys/switch-pen-insert' for '(null)' GPIO lookup
Note that callers of fwnode_gpiod_get_index() will still see the NULL
device pointer debug message, but there's not much we can do about that
because the API doesn't take a struct device.

The ACPI WMI specification states:
"The _WED control method is evaluated by the mapper in
response to receiving a notification from a control
method."
This means that _WED should be evaluated unconditionally even
if no WMI event consumers are present.
Some firmware implementations actually depend on this behavior
by storing the event data inside a queue which will fill up if
the WMI core stops retrieving event data items due to no
consumers being present
Fix this by always evaluating _WED even if no WMI event consumers

If a WMI event driver has no_notify_data set, then it indicates
support for WMI events which provide no notify data, otherwise
the notify() callback expects a valid ACPI object as notify data.
However if a WMI event driver which requires notify data is bound
to a WMI event device which cannot retrieve such data due to the
_WED ACPI method being absent, then the driver will be dysfunctional
since all WMI events will be dropped due to the missing notify data.
Fix this by not allowing such WMI event drivers to bind to WMI event
devices which do not support retrieving of notify data. Also reword
the description of no_notify_data a bit.

The unit for TPDM DSB element size is bits. So rename the property:
qcom,dsb-element-size => qcom,dsb-element-bits
This also makes it consistent with the naming for the CMB element
size property.
There is no tpdm node in any DT as of now. Make this change before
any tpdm node is added to DT.

All of the thermal_zone_device_register_with_trips() callers pass zero
writable trip points masks to it, so drop the mask argument from that
function and update all of its callers accordingly.
This also removes the artificial trip points per zone limit of 32,
related to using writable trip points masks.
No intentional functional impact.

It is now possible to flag trip points with THERMAL_TRIP_FLAG_RW_TEMP
to allow their temperature to be set from user space via sysfs instead
of using a nonzero writable trips mask during thermal zone registration,
so make the OF thermal code do that.
No intentional functional impact.
Note that this change is requisite for dropping the mask argument from
thermal_zone_device_register_with_trips() going forward.

Some Intel thermal drivers need/want the temperature of their trip
points to be set by user space via sysfs and so they pass nonzero
writable trip masks during thermal zone registration for this purpose.
It is now possible to achieve the same result by setting the
THERMAL_TRIP_FLAG_RW_TEMP trip flag directly, so modify the drivers
in question to do that instead of using a nonzero writable trips mask.
No intentional functional impact.

None of the users of the thermal core provides a .set_trip_hyst()
thermal zone operation, so drop that callback from struct
thermal_zone_device_ops and update trip_point_hyst_store()
accordingly.

In order to allow thermal zone creators to specify the writability of
trip point temperature and hysteresis on a per-trip basis, add a flags
field to struct thermal_trip and define flags to represent the desired
trip properties.
Also make thermal_zone_device_register_with_trips() set the
THERMAL_TRIP_FLAG_RW_TEMP flag for all trips covered by the writable
trips mask passed to it and modify the thermal sysfs code to look at
the trip flags instead of using the writable trips mask directly or
checking the presence of the .set_trip_hyst() zone callback.
Additionally, make trip_point_temp_store() and trip_point_hyst_store()
fail with an error code if the trip passed to one of them has
THERMAL_TRIP_FLAG_RW_TEMP or THERMAL_TRIP_FLAG_RW_HYST,
respectively, clear in its flags.
